Synthesis and some reactions of 2-acylcyclopentane-1,3-diones was written by Lakhvich, F. A.;Khlebnikova, T. S.;Akhrem, A. A.. And the article was included in Zhurnal Organicheskoi Khimii in 1989.Application In Synthesis of 2-(3-Methoxyphenyl)acetyl chloride This article mentions the following:

Acyloxycyclopentenones I [R = Me, hexyl, heptyl, PhCH₂, Ph, (CH₂)_nCO₂Et (n = 4-6)] were prepared in 88-97% yields by acylation of cyclopentanedione as its enol by RCOCl. Treating I with AlCl₃ in CH₂Cl₂ 3 h at -5 to 20掳 gave 68-96% acylcyclopentanediones II. Treating II [R = (CH₂)₄CO₂Et] with NH₂OH.HCl gave 86% oxime III which underwent Beckmann rearrangement to give 61% adipamic acid derivative IV. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0Application In Synthesis of 2-(3-Methoxyphenyl)acetyl chloride).

2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Application In Synthesis of 2-(3-Methoxyphenyl)acetyl chloride
